@dkliban fyi, if you were developing a workaround for this in oci_env, you no longer need to.

Presumably the before case, the tests were looking for ansible.cfg in CWD.

As far as I can tell, that is normally https://github.com/ansible/galaxy_ng/blob/master/ansible.cfg

It looks like that only exists to setup ansible tmp_dirs for use with ansible-importer. If importer tests work I guess it doesn't matter ?
